    • A method and apparatus for spectrum sensing of general wireless microphone signals are provided. The spectrum sensing algorithm developed makes use of the property that the spectrum of a wireless microphone signal resembles a tone-like spike, and that most wireless microphone operators use a pilot tone. Based on these properties, a simple spectrum sensing algorithm for the wireless microphone signal is designed based on frequency domain data processing without the large memory requirements of time domain methods and without the need for recursive memory accesses. The tones detected are further verified to see if they are located at one of the possible wireless microphone frequencies. The proposed method can determine the presence of wireless microphone signals even with strong adjacent channel interference.
    • 提供了一种用于一般无线麦克风信号的频谱感测的方法和装置。 开发的频谱感知算法利用了无线麦克风信号的频谱类似于音调尖峰的特性,大多数无线麦克风操作员使用导频音。 基于这些性质,基于频域数据处理设计了无线麦克风信号的简单频谱感知算法,而不需要时域方法的大存储器要求,而不需要递归存储器访问。 检测到的音调被进一步验证,以查看它们是否位于可能的无线麦克风频率之一。 所提出的方法即使具有强的相邻信道干扰也可以确定无线麦克风信号的存在。

    • A method and apparatus for identifying valid multipath energy peaks are described including locating an energy peak in a profile of energy peaks, categorizing the located energy peak based on a plurality of thresholds and processing energy peaks in at least one of the categories of located energy peaks. The method and apparatus further includes removing a direct current value component from each value in the profile of energy peaks, calculating a noise floor for a multipath searching window and determining a first threshold and a second threshold. The step and means for categorizing further includes determining if the located energy peak exceeds the first threshold, labeling the located energy peak as a false alarm, if the located energy peak does not exceed the first threshold, determining if the located energy peak exceeds the second threshold and labeling the located energy peak as confident, if the located energy peak exceeds the second threshold.
    • 描述了用于识别有效多径能量峰值的方法和装置,包括将能量峰值定位在能量峰值分布中,基于多个阈值对定位的能量峰值进行分类,并且处理能量峰值在至少一个定位的能量峰值类别中 。 所述方法和装置还包括从能量峰值分布图中的每个值中去除直流电流值分量,计算多路径搜索窗口的本底噪声并确定第一阈值和第二阈值。 用于进一步分类的步骤和手段包括确定所定位的能量峰值是否超过第一阈值,如果定位的能量峰值不超过第一阈值,则将定位的能量峰值标记为假警报,确定所定位的能量峰值是否超过第二阈值 如果定位的能量峰值超过第二阈值,则将所定位的能量峰值置于可信度上。
